After the pain of transferring all my data yesterday from my 2.5in HDD to my new SSD via USB (3-4hours for just 5gb Data lol) I was wondering if its possible to backup my partitions via WinUAE, this is how I prepare all my drives for classic setups and its much faster.
So I hooked up my old 2.5in HDD to my PC and ran WinUAE with OS3.9 (SmartFileSystem is in L:) the OS4.1 partitions show up in the early boot menu and HDToolBox can see them but they don't mount for use under OS3.9

I know OS4.1 can see partitions I prepared in OS3.9, but why not the other way round?
Is there any trick I can use? I don't mind modifying the RDB on this drive if I have to since it will be wiped and used in another machine.
Thanks in advance

Steve.
